Czech police say investigators have discovered another explosive at the Palestinian embassy complex in Prague where a possibly booby-trapped safe killed Ambassador Jamal al-Jamal on New Year’s Day.
Spokesman Tomas Hulan confirmed the discovery on Thursday, adding the unidentified explosive was sent for testing to Prague's Institute of Criminology. He declined to give details.
Police previously found 12 illegal weapons in a search following the January 1 explosion, prompting the Czech Foreign Ministry to accuse the Palestinians of breaching international obligations.
The Palestinians have claimed the weapons were not illegal.
It remains unclear what caused the safe to explode but the ambassador's death is being investigated as a case of negligence.
